Combined first trimester screening

Nuchal translucency ultrasound plus a blood test.

Pregnancy

Combined first trimester screening pairs an 11–13 week ultrasound measuring nuchal translucency with maternal blood markers to estimate the chance of chromosomal conditions. It attracts a Medicare rebate, unlike NIPT, and the ultrasound also checks early anatomy and dating.

Also known as: CFTS, nuchal translucency scan, 12 week scan
